If you're having trouble updating via the in-program updater, that is, it just sits there and doesn't update to the next version. You can try navigating to the GrooveWalrus folder you installed to (most likely c:\Program Files\GrooveWalrus) and running gw.exe from there, then update. If this happens/works for you let me know what version of Windows you're using and if your running from a desktop icon or GrooveWalrus is pinned to the taskbar.
